{4.5/5} “‘I don’t believe this place exists, at least physically. Instead I think we’re all participating in some kind of… collective hallucination or simulation.’ When she said it aloud, Una realized it sounded more than a bit farfetched. Sarek seemed to ponder this, but only for a moment. ‘A shared mental construct.'”

Kirk has retrieved the Transfer Key, but not before more people were whisked away to the other realm — Sarek and Joanna McCoy. Kirk needs to get back to Usilde to rescue them as well as Captain Una and hopefully the rest of her team. But the planet is now under the control of the Klingons. Meanwhile, Sarek, Joanna, and Una are in the realm of the Jatohr and finding that it’s very different from anything else they’ve experienced.

This is the 3rd book in this trilogy, and it fittingly concludes the story. Although the books were written by different authors, the transitions are seamless.

In addition to the crew of the Enterprise we get to see Captain Una, Sarek, Amanda Grayson, Joanna McCoy, and Councillor Gorkon.

It’s about exploring a new realm, and communicating with prickly aliens.
